MT#55283 fix DB metadata output

Delay writing of call DB entry until a metadata has been set, even if
empty. This is so that we can know whether "skip DB" was set or not.

Check DB entry status with every event, not just when streams are
created. Stream may get created before all relevant data for DB entries
is there.
